DRIVER FOR WHEELS, SHAJETS, AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 22, 1921.

To all to hem it may concern Be it known that I, ANnnns JOHAN Euros- SON MUNTERS, a subject of the King of Sweden, and resident of Luntmakaregatan 7, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Drivers for lVheels, Shafts, and the like, (for which I have filed an application in Sweden, No. 3688, dated November 14, 1917,) of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to an improved cou pling device for Wheels, shafts and the like, of that class in which connecting rollers are used whereby during the rotary motion of the driving member in one direction said rollers will exert a wedging action between the driving and driven members, and which rollers automatically become disengaged from the driven member upon cessation of rotation of the driving member.

A further object of the invention is to provide a coupling device of the character set forth in which the use of springs is entirely eliminated.

A further object of the invention is the provision of a coupling device of the character set forth, in which tubular rollers are symmetrically located between the driving and driven members, and means for limiting the travel of the rollers relatively to the driving and driven members.

With the foregoing and other objects in view, the invention consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the claims. I

In the drawings accompanying and forming part of this specification- Figure 1 is a transverse sectional view of a coupling device constructed in accordance with the present invention;

Fig. 2 is a longitudinal section of the device shown in Fig. 1;

Fig. 3 is an end view of a device similar to that shown in Figs. 1 and 2, but provided with means for shifting the position of the pins for limiting the travel of the rollers;

Fig. 4 is a longitudinal section of the de vice shown in Fig. 3; and

Fig. 5 is a transverse sectional view illustratin a further modification of the device.

S innlar characters of reference designate the same parts in the different figures of the drawings.

Referring particularly to Figs. 1 and 2 of the drawings, 1 illustrates a driving member, such for instance as a shaft, which may be actuated by any suitable means, such as a motor (not shown). To said shaft is secured one member of the coupling device in the form of a sleeve 2, thereby forming the driving part of the coupling. The driven member of the coupling comprises a triangular member 3 mounted for rotation on the shaft 1. To the member 3 are secured, as for instance by brazing or in any other suitable manner, a pair of plates or disks 5 and 5? respectively, one on each side of the triangular member 3, these disks being of such a diameter as to permit them to rotate within the sleeve 2 of the driving member, and the disk 5" is adapted to be secured to any member, such as the hub 5 of a vehicle wheel, to which it is desired to transmit the rotary movement of the shaft 1. In the channels formed between the plates 5 and 5 are 10- lated a plurality of tubular rollers 4, one in position to contact with each of the sides of the triangular member 3, the travel of the rollers being limited by means of pins 6 secured in the disks or plates 5 and 5 said pins being of a diameter considerably smaller than the inner diameter of the rollers thereby to permit said rollers to have radial movement relatively to said pins.

From the foregoing construction, it will be obvious that if the driving member 2 is rotated, for instance in the direction indicated by the arrow in Fig. 1, while the driven member 3 remains stationary, the rollers 4: will be carried along with the driv ing member until the rollers become jammed between the inner surface of the driving member 2 and the flat side of the driven member 3, whereby the member 3, and with it the hub 5 will also be caused to rotate with the driving member 2. When, however, the rotation .of the member 2 ceases, the momentum of the driven member will cause the same to continue to rotate a short distance, and this rotation will release the rollers from their jammed position andjallow them to assume the inoperative position shown in Fig. 1. It will be observed that the pins 6 are located at a point which is at one side of the center of the length of the flat side of the member 3. The purpose of so locating the pins 6 is to prevent the jamming of the rollers at the opposite ends of the bat sides of the triangular member 3. That is to say, when the rotation of the driving member 2 has ceased and the driven member 3 continues to rotate as above described, the rollers will become disengaged from the driving member, but will be prevented from traveling sufficiently far toward the opposite point of the flat side of the member 3 to permit them to become jammed, because the inner sides of the rollers will be engaged by the pins 6 before they can pass the widest portion of the space between the inner surface of the driving member 2 and. the flatside of the memher 3. r

In the form shown in Figs. 3 and 4:, I

I have illustrated meanswhereby the conpling members can be adjusted for operative engagement in either direction. In this form of the device, the sleeve member 2 is shown mounted for rotation on the end of the shaft 1, it being retained on said shaft by. means of a flanged head 12 formed on {the shaft and operating in a socket formed on the rear end of the sleeve 2 The member 3 is of the same form as that shown in Figs. 1 and 2 and has secured thereto the platesor disks 5 and 5 in the same manner as shown in said figures. In this instance, however, the plates 5 and 5 are provided with elongated slots 11 for the passage of the pins 6, which pins extend through the plate 5 and are each secured in one of the arms of a three-armed member 9, which is adapted to shift the pins from one end of the slots 11 to the other. This member 9 is adapted to be clamped between the plate 5 and a wing nut 10 which is threaded on the shaft 1, as clearly shown in Fig. 4:. By means of this construction, upon releasing the wing nut the member 9 may be shifted on theshaft 1, circumferentially thereof, so that the pins 6 may be moved from one end of the slots 11 to the other and locked in position by turning the wing nut 10 so as to clamp the member 9 to the plate 5. From this construction, it will be seen that when the arms of the member 9 are in the position shown in Fig. 3, it being remembered that the rollers 1 are of the same construction as illustrated in Figs. 1 and 2, that is to say, the inner diameter thereof is such that they have a floating movement around the pins, if the shaft 1 is rotated-in the direction of the arrow in Fig. 3 the pins 6 will engage the side walls of the rollers and cause the same to wedge be:

tween the members 2* and 3. Should it be desired to adjust the coupling so that such vedging action will take place when the shaft 1 is rotated in the opposite direction,

the opposite ends of the slots 11 and the wing nut again clamped on the member 9.

The structure shown in Fig. 5 is identically like that shown in Fig. 1, except that the member 3" is of slightly different form from the member 3 shown in Figs. 1 and 2, but the operation of the device is the same.

It will be understood,rof course, that while I have described certain members as driven members and others as driving members, either of such members may be the driving member and the other the driven member,and that the coupling may be used in all cases Where two rotatable members are to be detachably connected for rotation together, and while I have described in detail the structures herein illustrated, it is to be understood that I .do not thereby limit my invention to the precise features of con struction shown, as I am aware that many mechanical changes and modifications may be made therein without departing from the spirit and scope of the appended claims.

Having thus described my invention what I claim is angular member rotatable within the cylindrical member, a pair of disks secured to said triangular member, a plurality of rollers disposed between said disks and each having a floating movement between one side of the triangular member and the inner surface ofthe cylindrical membeigand a pin passing through each of said rollers and said disks at one side of the center of the length of the side of the triangular member for limitingthe floating movement of the rollers thereby to cause the same to engage the cylindrical and triangular members for rotation together in" one direction.

2. Acoupling devlce, comprising a cylindrical member and an approximately triment of the rollers thereby to cause the same to engage the cylindrical and triangular members for rotationtogether in one direction, and means for shifting the pin to the opposite side of the center of the length of the side of the triangular member.

3. A coupling device, comprising a cylindrical member and an approximately triangular member rotatable within the cylindrical member, a plurality of rollers between said members and each having a floating movement between one side of the triangular of said rollers and disposed at one side oi? the,

center of thelength'of the side of the trian ular member for limitin the fioatin 23 b b movement of the rollers thereby to cause the same to engage the cylindrical and triangular members for rotation together in one direction, and means for shifting the pin to the opposite side of the center of the length of the side of the triangular member, said means comprising a member rotatable relatively to said triangular member and in which said pins are secured, and means for releasably clamping said rotatable memdrical member and an approximately triangular member rotatable within the cylindrical member, a pair of disks secured to said triangular member and provided with elongated slots, a plurality of rollers disposed between said disks and each having a floating movement between one side of the triangular member and the inner surface of the cylindrical member, a pin passing through each of said rollers and through the slot! of said disks, means for shifting the pins from one end of the slots to the other, and means for releasably clamping said last means to the triangular member.

In witness whereof, I have hereunto signed my name.
